#just imagine for me alison finding this old picture of her gran and her gran’s sister

The Captain is more closely related to Alison than any other member of Button House

And here's why.

Warning: spoilers for season seven of Call The Midwife, extreme speculation, and the use of headcanons to forward that speculation lay ahead, read at your own risk.

The factuality of this statement hinges entirely on one headcanon, and that is:

- The Captain has at least one sibling, an older sister, and she looks somewhat like Alison.

I could argue for days on the stance that the Captain is a middle child of many siblings, but that's a post for another day.

I pin this sister's birth year to be around 1897, and as such would be in her late thirties or bang on forty for the birth of her two children (incoming Call The Midwife link) Margaret and Barbara.

In the show, Barbara (the younger of the two) is played by Charlotte Ritchie, so it only stands to reason that both her mother - the Captain's sister - and her sister Margaret would also have similar features. But unfortunately Barbara cannot be our linking thread due to her untimely death, Margaret on the other hand is free and entirely unknown.

If Margaret were to marry and have a daughter of her own, the timelines would match up splendidly for that daughter to be Alison's mother after marrying that distant Button. (Being that the Button connection is on her father's side, it doesn't interfere and is therefore entirely plausible.)

To put a long story short, the Captain's sister married a man named Arthur Gilbert with whom she had two daughters, and one of those daughters was Alison's grandmother, making the Captain Alison's great-granduncle.

Never leave me alone with unknown family histories in the throes of hyperfixation or I just might find a link between the most distant characters.
